Pokemon Scarlet and Violet's The Indigo Disk DLC handles Legendary Pokemon encounters a little bit differently than past games in the series. There are almost 30 of them to catch, but players will not be able to access them until they complete the main storyline of the expansion and roll credits. After doing so, you can meet a man in a black suit named Snacksworth, who hangs out near the front entrance of Blueberry Academy.
